--.'Application=fi1ed March 26, 1915. eSeria1;No..17,214.

To allwkom it may concern Be it known that I, 'LEMUEL JMCI{INNON,

citizen .of the United States, residing. at

Salt .Lake City, ,in the. countyofSalt :Lake

.and.-State of Utah, have invented a newand vuseful Tire, of which .the .following as. a. specification.

-;The device forming the subject. matter of .thisaapplicationis a resilienttire and the inventionaims primarily, toprovide ainovel con1bination ofresilient elements which cooperate to .give themnecessary .sprmgcet'fect 1 tothe-L tire.

Itpis within-i the scope of therdiscl'osure .to improve generally and-t0 enhance the utility of devices of that type. to which the present invention appertains.

. Withthe above and other objects in view,

.Whichwill appear as the description proceeds, the lnventionresides lnthe combinat1on and arrangement of parts -LI1d..1I1'tl16 details.- of constructionhereinafter described and claimed, it being understood that changesin theprecise embodiment ,of the invention .herein .disclo-sed can be..made Withinthe scopeofwhat is claimed,without .;departing fromthe spirit ofthe invention.

In theaecompanying drawings: Figure 1 shows the invention in vertical circumferentlalsectlon, parts appearing; 1n elevation;

Fig. 2 isa cross section: taken strictly on the 1, distant parts being fragmental top plan, parts being successively broken awavand Fill; 4 is. a fragmental-top plan showing the connected ends of the. tightenfragmental; longitudinal section showing a modifiedmeans ,for

connecting the ends of the band.

In carrying out the present invention there is provided a rim 1 equipped with any desired means for holding. a tire casing 3 which, as usual, is divided along its median line, adjacent the rim 1. In the present instance, but not of necessity, the riml is equipped with clencher-flanges .2 engaging thecasing .3. Located within the casing 3 and conforming to the interior crcsssection of the caslng is a tubular lm1ng4=wh1ch may ,bemadeof canvas.

SCI'QKVS .14 and-threaded into thearmlO.

Disp osed,within the lining tare a.p1urality pfmesilient blocks 5,..spaced apart .circnniferentia'lly of i the .tire. :The blocks 5 may be made of rubber or some, composition @ha-vingthev desired, resiliency. The blocks 5 ,are disposed, adjacent 1 the tread portion of ,the liningt and conform closely to the interior contour .ofthe lining-A throughout. a portion ,of the cross section thereof, the iblockspreferablytbeingin the form of seg- .ments'-. of .circles in cross section. .faces16 of the blocks 5 are disposed .at'an 'acute.ang1e to themedian plane of the tire, .as indicated clearly in Fig. :3, so. that the The end weight may .come onto one block before it .is entirely off anadjo-ining block.

The resilientblocks 5 rest on aresilient, d1v1ded .band, the same ordinarily being may be con- .r1vets8 or The band which is composed of thestrips is united at its ends by angle members. one end of. the strip being recessed to receive. the .circumt'erentialarm 9, ot one angle member, i. the radial arm of which is denoted by the numeral .10. This angle member-and an- ,other; angle..member to be described. hereinrat nt a wa -zl ism after are connected with-[the .respectiveends .ot' the,.,band by meansof rivets .1l-or,,other isecuringelements adapted to a likepurpose. The other angle member comprises a circumferential ar1nl2wand Laradial arm 14,.the

arm] 12. being equipped with a circumferential tongue. 15 bridging the space between the .armslO andv i l .of the respective angle members, and slidably received in .a .recess .16

tormed in: the arm-9 of one angle member. The inwardly projecting arms 10 and 1a of theangle members maybe united adjustably by any suitable meansysuch as one orsmore 17 journaled for rotation in the arm One means for securing the resilient blocks 5 to the resilient band composed of the strips T-is a lacing cord 18 passed spirally through. openings, in the blocks and the contour of the-lining l is an inflatable e 7 tube 19 provided with a plurality ofcircumferentially spaced, outwardly projecting fact that, as shown in Fig. 3, the blocks 5 are beveled at 6 so that cells 20, the tube proper 19 and. each cell 20 being of a size to fill the cross sectional'a'rea V defined by a portion of the liningA and the band composed of the strips 7. The tube 19 and its cells 20 are inflated by means of a valve tube 21 extended inwardly through the rim 1 as will'be understood best'from Fig: 1

of the drawings.

of a canvas tube flattened down so that its opposed portions are in contact, Fig.1 being referred to for a clear understanding of this detail.

A means is provided for drawing the extremities of the tightening band 22 to- 1 1 gether, and with this end. in view there. is provided a block 23 preferably of metal and conforming approximately to thefcross section of the tightening band 22. 'The block or strip 23 includes a tongue" 24 passing between the constituent layers of the band 22 f and held theretobyimeans ofrivets 25 or the like. "The'otherend of thetightening band 7 22 is. provided with a stripor block 26 in- 351 cludinga tongue'2 7 heldinplace by rivets '28 asbefore. A pair of screws29 are held atone end in thestrip 26 and'are adapted to move longitudinally in slots 30:1I'ormed in the strip or block 23. The slots 30 are provided with transverse extensions 31,freceiv- 'ingfor rotationfbut against movement circumferentially of the tire, worm wheels 32 operated by means ofa radial worm'33provided with an exposed wrench head 34, the

worm 33 projecting through an opening 35 in thetire 3. 'In order to prevent the wormfrom moving toward the tread of the-tire,

when the worm is rotated, a thrust plate36 is attached totheblock or strip 23-. and en Y 7 7 I portion of the casing; In practical operation, the tightening band 22 maybe drawnup by actuating thegages one end of the worm.

worm 33,'the same rotating'the worm wheels 32 which, being threaded upon the screws 29, will serve to tighten up theband 22. 7 At this point :it maybe noted that the valve tube 21 liesbetween the strips 23and 26,

and preferably is 1 disposed between the screws 29 as will be understood when Fig.

1 is compared with Fig. 4. The tube 19 maybe inflated readily, the tube and its cells 20 being expanded so that the latter bear against the. band c'omposedof the strips 7.

Owing to the fact that the cells '20 are member 104." The angle members found satisfactory.

I casing an inflatable tube spaced apart circumferentially of thetire,

the band composed of the'strips 7is per-. mltted to give to some extent between the cells Further, owing to the fact that the resilient blocks 5 are spaced apartcircumferentially of the,tire, the resiliency of the latter is enhanced butin this connection it is to be observed that the tire will operate without any bumping efiect, owing to the r they overlap, circumferentiallyi' of the device.

In the modification shown in Fig. 5, the

inner band strips are shown at 100, the
